These ovens require a vacuum source. The oven does not come with a vacuum pump.
Use of an oil trap plumbed on the vacuum line between the oven and the pump is strongly
recommended. The trap protects the pump from any oils outgassed during your baking application or
procedure. This extends the life of the pump. All maintenance and instructional information should be
obtained from the pump manufacturer if it was not shipped with the pump.
Mounting studs and an electrical outlet for powering a vacuum pump are installed in the cabinet inside
the base of the oven. See the
Connect to the Vacuum Supply entry in the Installation section (page
30) for more information on the oven vacuum plumbing.
Minimum Pump Evacuation Rate
For the chamber to seal, the vacuum pump must be able to evacuate at least 1 cubic foot per minute
(cfm) for each cubic foot of oven chamber volume (CuFt).
In other words, 1 pump cfm per oven chamber CuFt.
Model Chamber Capacity Min. Pump Capacity CFM Min. Pump Capacity LPM
CVO-2-HT 1.67 CuFt 2 cfm 57 Liters per Minute
CVO-5-HT 4.50 CuFt 5 cfm 142 Liters per Minute
To seal completely, the oven chamber must be under a minimum vacuum of:
